IAID FOR ARTIFICIAL TEETH AND METHOD-OF PREPARING SAME.

Original No. 1,577,134, dated March 16, 1926, Serial No. 6,310, filed February 2, v 19 25. Application for reissue filed February 10,

The present invention relates to dental devices, and more particularly to means for use in connection with dental plates, whereby the discomfort ordinarily incident to the useof artificial teeth may be ,materially reduced, and, in many instances, eliminated.

Many persons find great diflieulty in keeping the lower plate position, and a very general complaint is-that the plate causes a1- nostconstant annoyance and pain.

Thedifiiculty is due very often to the fact that there is a smalhbut nevertheless perceptibleshrinkage of the gum after the plate has been ,worn forsome time, so that there results considerable playanddooseness of the plate,- although when first fitted it may have been oftheproper dimensions. When it becomes loose, the plate, since it is comparatively hard rubs and irritates thegum;

An objectof the present invention is to provide, a pad or cushion tobe interposed between the lower plate and the gum and adapted to relieve the pressure upon the ,gum and afiorda suflicicnt suction to hold the plate n pl c i A further ob ect of the inventionis to provide a cushion or pad which will be thoroughly aseptic, may bequickly ap lied to the plate,.and ,whichwill retain its s iape pad applied.

material, such as cotton.

fFigure 2 is a perspective view showing the paid at an intermediate stage and before it is bent to U-shape.

tainits shape. The solution may be of aseptic character so as to have a soothing or healing effect. It has been found that one containing boric and benz'oic acids, such as listerine, is highly satisfactory. This prodnot, under the action of heat, suitably stiifens ghe pad to retain the ,U-shape to which it is ent.

After saturation, the roll is bent to the U shape shown in Figure 3, and at its middle portion there is formed a lip 13 which will fit over the inner edge 14 of the plate. The lip may be formed b placing the roll in amoldor. other suitab e shaping device, and in order that it may remain after the molding operation, the lip sliould, prefer ably, becoated with a stifi'ening agent,such as acacia. g

The (1-011, while stillin itsiufshape, and if desired, While .in the mold, should be subjected to heat sufficient to dry the acacia and the aseptic solution. When removed from the mold after treatment with heat,

the lip 13 will be comparatively hard and the remainder of the pad, while soft, is sufficiently stiff to maintain the form impart-ed to it .by the mold. Thus, there is no necessity for tying or wrapping meanstoprevent disintegration of the pad, and yet, under the action "of moisture when in use, the entire pad will become relatively soft, since .the stiffening action of the aseptic solution talking. Although the stiffening action of the dry aseptic solution is quickly overcome by the moisture, the aseptic effect remains for a prolonged period, thus affording the desired protection and preventing a drying or parching sensation when the cushion is inserted.

' It should be understood that numerous changes may be made in the embodimentof the invention illustrated and described with- .out departing from the invention which is defined by the followfn gv claims,
